Title: Spatial light modulator with improved peak white performance
Inventor: MARSHALL STEPHEN W
IPC: G02F1/01
Filed: 1996-06-19
Abstract: A spatial light modulator based imaging system (30) with improved peak white performance characteristics. The apparent dynamic range of the spatial light modulator (74) is increased by adding light to pixels neighboring a saturated pixel. An apparent bloom effect is created with the pixels neighboring the saturated pixel appearing brighter, to give sunlight reflecting from the surface of a lake, for instance, more sparkle or highlights. Charts or equations are utilized to determine the degree to which pixel brightness is increased for neighboring pixels. The closer a pixel to a saturated pixel, and the greater the saturation of a particular pixel, the greater increase in brightness for neighboring pixels.

Title: Bus monitor system
Inventor: SOUTHWAY JAMES B JR
IPC: G06F11/34
Filed: 1996-10-03
Abstract: BUS MONITOR SYSTEM        A bus monitor system comprises eight identical pro-grammable monitor circuits that are each connected to a monitored bus and to a local 16-bit event bus. There are three interfaces to they event bus within each monitor circuit. one interface asserts a predetermined bit pat-tern on the event bus when match conditions occur between bit patterns on the monitored bus and predetermined bit patterns stored in monitor circuit registers. A second interface asserts a signal on an external pin when bit patterns on the event bus match a predetermined bit pat-tern stored in a monitor circuit register. A third inter-face asserts a predetermined bit pattern on the event bus when an external device has asserted a signal on an ex-ternal pin. Each monitor circuit is capable of reading and asserting any of the bits of the event bus. The event bus is used to enable or disable monitor circuit inter-faces. If any asserted bit on the event bus matches a corresponding bit of one of the predetermined bit pat-terns stored in the interface enable and disable regis-ters, that interface will be enabled or disabled, respec-tively. The event bus gives the monitor system the abil-ity to simultaneously monitor for multiple bit patterns on the monitored bus, and to monitor for a sequence of bit patterns by halving one monitor circuit trigger another.

Abstract: A turn assisting mechanism assists a turning motion of a vehicle,  such as a lawn mowing vehicle,  so that the vehicle may not damage the ground (lawn grass, crops, etc.) when the vehicle makes a U-turn.   The turn assisting mechanism is disposed near a wheel of the vehicle nearest to the center of turning of the vehicle about which the vehicle makes a U-turn.   The turn assisting mechanism stretches out the rod of a hydraulic cylinder  actuator to set a ground contact unit on the ground and lifts up the wheel nearest to the center of turning of the vehicle. When the vehicle makes a U-turn, the hydraulic cylinder actuator sets the ground contact unit on the ground so that the axis of turning of the ground contact unit passes the center  of  turning  of  the  vehicle,  and  lifts  up  the corresponding wheel from the ground.  The vehicle makes a U-turn on the ground contact unit without damaging the ground.
